          Islamic Leadership, Islamic Work Culture, and Employee Performance: The Mediating Role of Work Motivation and Job Satisfaction

          ASTUTI,,Sih,Darmi,SHODIKIN,,Ali,UD-DIN,,Maaz Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.11

          This study aims to examine the influence of Islamic leadership and Islamic work culture on employee performance through work motivation and job satisfaction. This study was conducted at Universitas Islam Negeri (UIN) Walisongo Semarang, Indonesia, because so far, there is still very limited research on the relationships between Islamic leadership, work culture, and work motivation in educational personnel performance. The educational personnel performance is expected to increase at UIN Walisongo Semarang with continuous efforts to improve to survive and develop as much as possible. The population of this study was all educational personnel at UIN Walisongo Semarang, Indonesia. Of 186 people, only 127 people were involved in this study. The research method used was a survey method using primary data collected through questionnaires. This study's analysis technique employed multiple linear regression. The results uncovered that, out of the eight hypotheses proposed, six hypotheses were accepted. Islamic leadership and Islamic work culture were found to have no direct effect on employee performance. Besides, work motivation and job satisfaction became essential factors mediating Islamic leadership and Islamic work culture on employee performance. Spiritual values in leadership inspire employees to build the organization's vision and create job satisfaction, which in turn impacted employees' performance.

        • Pyrophen Produced by Endophytic Fungi Aspergillus sp Isolated from Piper crocatum Ruiz & Pav Exhibits Cytotoxic Activity and Induces S Phase Arrest in T47D Breast Cancer Cells

          Astuti,,Puji,Erden,,Willy,Wahyono,,Wahyono,Wahyuono,,Subagus,Hertiani,,Triana Asian Pacific Organization for Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.2

          Ethyl acetate extracts obtained from culture of endophytic fungi Aspergillus sp isolated from Piper crocatum Ruiz & Pav, have been shown to possess cytotoxic activity against T47D breast cancer cells. Investigations were here conducted to determine bioactive compounds responsible for the activity. Bioassay guided fractionation was employed to obtain active compounds. Structure elucidation was performed based on analysis of LC-MS, $^1H$-NMR, $^{13}C$-NMR, COSY, DEPT, HMQC, HMBC data. Cytotoxity assays were conducted in 96 well plates against T47D and Vero cell lines. Bioassay guided isolation and chemical investigation led to the isolation of pyrophen, a 4-methoxy-6-(1'-acetamido-2'-phenylethyl)-2H-pyran-2-one. Further analysis of its activity against T47D and Vero cells showed an ability to inhibit the growth of T47D cells with IC50 values of $9.2{\mu}g/mL$ but less cytotoxicity to Vero cells with an $IC_{50}$ of $109{\mu}g/mL$. This compound at a concentration of 400 ng/mL induced S-phase arrest in T47D cells.

          Nutrient Balance and Glucose Metabolism of Female Growing, Late Pregnant and Lactating Etawah Crossbred Goats

          Astuti,,D.A.,Sastradipradja,,D.,Sutardi,,T. Asian Australasian Association of Animal Productio 2000 Animal Bioscience Vol.13 No.8

          A study involving nutrient balances and radioisotope labeling techniques was undertaken to study energy and protein metabolism, and glucose kinetics of female crossbred Etawah goats, using 12 weaned (BW $14.0{\pm}2.0kg$), 12 late pregnant (BW $27.8{\pm}1.8kg$) and 12 first lactation does (BW $25.0{\pm}5.0kg$). Each class of animal was randomly allotted into 3 dietary treatment groups R1, R2 and R3, that received 100%, 85%, and 70% of ad libitum feed. The rations offered were pellets containing 21.8% CP and 19.3 MJ GE/kg, except for the lactating does who received pellets (17.2% CP and 18.9 MJ GE/kg) and fresh Penisetum purpureum grass. Energy and nitrogen balance studies were conducted during a two-week trial. Daily heat production (HP, estimated by the carbon dioxide entry rate technique), glucose pool and flux were measured. Equations were found for metabolizable energy (ME) and protein intake (IP) requirements for growing goats: ME (MJ/d)=1.87+0.55 RE-0.001 ADG+0.044 RP $(R^2=0.89)$ and IP (g/d)=48.47+2.99 RE+0.029 ADG+0.79 RP $(R^2=0.90)$; for pregnant does: ME (MJ/d)=5.92+0.96 RE-0.002 ADG+0.003 RP $(R^2=0.99)$ and IP (g/d)=58.34+5.41 RE+0.625 ADG-0.30 RP $(R^2=0.98)$; and for lactating does: ME (MJ/d)=4.23+0.713 RE+0.003 ADG+0.006 RP+0.002 MY $(R^2=0.86)$; IP (g/d)=84.05-5.36 RE+0.055 ADG-0.16 RP+0.068 MY $(R^2=0.45)$, where RE is retained energy (MJ/d), ADG is average daily gain in weight (g/d), RP is retained protein (g/d) and MY is milk yield (ml/d). ME and IP requirements for maintenance for growing goats were 0.46 MJ/d.kg $BW^{0.75}$ and 7.43 g/d.kg $BW^{0.75}$, respectively. Values for the pregnant and lactating does were in the same order, 0.55 MJ/d.kg $BW^{0.75}$ and 11.7 g/d.kg $BW^{0.75}$, and 0.50 MJ/d.kg $BW^{0.75}$ and 10.8 g/d.kg $BW^{0.75}$, respectively. Milk protein ranged from 3.06 to 3.5% and milk fat averaged 5.2%. Glucose metabolism in Etawah crossbred female goat is active, but glucose flux is low compared to temperate ruminant breeds which may implicate its role to support production.

          “They Had Peer Preference” : A Portrait of Tensions in Cooperative Learning Implementation in EFL Classrooms

          Puji,Astuti,Jayne,C.,Lammers 아시아영어교육학회 2020 The Journal of Asia TEFL Vol.17 No.2

          Despite an increase in research on the effects of cooperative learning (CL) on EFL learning, few studies explore the processes occurring within the use of CL and even fewer depict challenges with CL implementation. To address that gap, this qualitative multi-case study explored the important roles that individual accountability − CL's key principle − play in enhancing EFL learning and was guided by the following question: How does missing the activities that demonstrate individual accountability in CL affect EFL learning? Data were generated by participant observations, in-depth interviews, and document analysis to conduct an empirical examination of what teachers and students experience, namely that while CL was part of teacher participants' instructional practice, the procedures of some selected CL structures were only partially followed by these teachers. When CL was not implemented with fidelity, performances of individual accountability in home groups and peer interactions were missed. With a Cultural-Historical Activity Theory lens, this analysis provides a portrait of tensions in the CL implementation, such as one between EFL learners (subjects) and the EFL classroom (community); it was evidenced by the learners having peer preference, i.e., taking the attitude that not all of their peers could be their resource person.

          The Effect of Perceived Organizational Support and Transformational Leadership on Affective Commitment and Employee Performance

          Isthofaina,ASTUTY,Udin,UDIN 한국유통과학회 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.10

          Recognizing the vital role of employees in achieving optimal performance and sustainable competitive advantage as expected, organizations need to facilitate high support for employees, implement appropriate leadership styles, and increase affective commitment within the organization. Therefore, the objective of this study is to analyze and explore: (1) the effect of perceived organizational support (POS) on employee performance and affective commitment; (2) the effect of transformational leadership on employee performance and affective commitment; and (3) the effect of affective commitment on employee performance. The covered population in this study were all employees (including managers, supervisors, and functional staff) who worked in the stone milling companies in Central Java, Indonesia. Data obtained in this study were processed statistically employing structural equation modeling (SEM) with the SmartPLS 3 software package. Based on the data analysis results on 103 respondents, this study concluded that POS had a significant effect on affective commitment and employee performance as well as transformational leadership on affective commitment and employee performance. Furthermore, affective commitment also had a significant effect on employee performance. Thus, the results of this study, theoretically and practically, can be used by all parties concerned to improve employee performance and maintain a sustainable competitive advantage.

          Effect of  density between  intercropped sorghum and  stylosanthes on biomass production and quality under varying NPK fertilizer application rates

          Dian,Astuti,Bambang,Suhartanto,Nafiatul,Umami,Agung,Irawan 한국작물학회 2020 Journal of crop science and biotechnology Vol.23 No.3

          This field study was conducted to investigate the effect of spaced-row pattern and NPK fertilizer rates on productivity and quality of inter cropped sorghum and Stylosanthes guianensis. Three spaced-row pattern (S1 = 90x20 cm, S2 = 75x25 cm, and S3 = 60x30 cm, respectively) and NPK fertilizer application rates (N1 = 0 without NPK, N2 = 100 kg/ha, N3 = 200 kg/ha, respectively) were investigated under two local sorghum varieties (V1 = var. Kawali and V2 = var. Super-2) in a 2x3x3 split-split-plot design. Intercropped sorghum x stylosanthes in S3 resulted in higher dry matter (DM) content and biomass production than that in S1. NPK fertilization significantly increased DM and organic matter (OM) production by 16.2–115.0% and 16.1–115.2%, respectively, compared to those without NPK fertilization. Interaction effects of V x NPK and V x S x NPK were detected that contributing to the increase in biomass and nutrient quality of the forages. In vitro DM and OM digestibility rates for V1-S were higher than at V2-S. In conclusion, V2 produced a higher biomass, whereas V1 was superior in terms of nutrient quality. Spaced-row at 60x30 cm and 100 kg/ha of NPK were efficient in improving the productivity and nutrient quality of sorghum and stylosanthes.

          Individual Accountability in Cooperative Learning in EFL Classrooms: More Opportunities for Peer Interaction

          Puji,Astuti,Leslie,Barratt 아시아테플 2018 The Journal of Asia TEFL Vol.15 No.1

          Research shows that cooperative learning (CL) supports foreign language learning (e.g., Almuslimi, 2016; Wei & Tang, 2015). However, there is little research demonstrating how CL works and, specifically, how it promotes learning, particularly individual accountability, which is a principle in CL. This article reports on part of a larger study that aimed to fill this gap by exploring the roles of individual accountability in CL in enhancing EFL learning. The study involved two secondary school EFL teachers, with 77 students in their classrooms, and four focus students. Analysis of data from participant observations, in-depth interviews, and document analysis shows that individual accountability manifests itself in a series of activities from individual, group, and class presentations as well as other peer interactions. The findings also showed that the learners had more opportunities to interact and had more interactions with their peers during CL than during conventional group work (i.e., students simply completing non-CL activities in groups). Opportunities for student-student interactions in CL activities, absent in the conventional group work, may have contributed to the EFL learners' communicative competence. However, teachers new to CL should follow the preset procedures for CL strategies to promote individual accountability and understand how these activities benefit students.

          Country of Origin, Religiosity and Halal Awareness: A Case Study of Purchase Intention of Korean Food

          Yuni,ASTUTI,Daru,ASIH 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.4

          This research empirically analyzed whether the foods which came from a non-Muslim majority country, such as South Korea, could play an important role in affecting the consumer intention in a predominantly Muslim country. Online survey methods were used to investigate the proposed hypothesis. 318 responses were used for further analysis. Forty-six reflective constructs were adapted from literature and designed by using a five-point Likert scale to facilitate measurement. Estimation models and structural models were examined through SEM-PLS analysis techniques using SmartPLS 3.0 application as the data processing tool. The results showed that religiosity and halal awareness had a positive and significant effect on attitude toward halal labels, including the mediating effect from consumer attitudes towards halal labels which had a positive but insignificant effect on purchase intention. Halal awareness plays an important role for Muslims in the decisionmaking process for purchasing food. In contrast to the initial hypothesis, the country of origin actually did not have a positive effect on attitudes towards the halal label. In a Muslim-majority country like Indonesia, findings halal food is not difficult, so this research basically is a reminder to marketers to follow those halal principles in implementing their marketing strategies.
